HTC Europe director Mark Moons caused quite a stir this morning when he tweeted that the company would begin rolling out Android Froyo updates to devices tomorrow, starting with the Desire, but we wouldn't get too excited yet -- HTC tells us that it's possible a rollout will begin tomorrow, but nothing's finalized yet pending some final testing. We've certainly got our fingers crossed -- and we're sure Desire owners the world over will be hitting that System Updates button nonstop for the next few days.
